I rented an apartment in a two-family house with two residential units in it. The landlord occupies the upstairs unit and I occupy the bottom unit. There is only one shared mail box. My landlord has been removing the mail and leaving mine on a little table in the shared hallway. I have asked for a separate mailbox, but received no response. Is it legal for the landlord to rent a separate residence to me without providing me with a separate mailing address or a separate mailbox. I am especially worried that he is stealing or disposing of my mail because I am now in a dispute with him regarding many other problems with the apartment.
